I ride the subway to work for a stretch, and was getting really annoyed with SK AP's in the subway car cutting me off while surfing.

Lately I have noticed that while streaming background music from an app like 8tracks, I no longer lose connection and my browsing experience suffers no issues (in fact, pages load faster). If I leave 8tracks off, then same old cut-offs return randomly, and my wifi goes searching for the signal again. This has led me to wonder if a constant signal keeps your phone from being cut off of the AP while in a high use environment or something?

If anyone else could try it and see if it improves things for them, please let me know.

Was discussing this with a phone store. They said it had to do with getting bumped by other users after not accessing for a time. So the music idea works. Of course you can also get booted just changing ap's.

I have noticed when I am near a station I lose reception - I assume that it is something to do with the router in the station and the one oin the car conflicting with each other...

Is this the case ?

Yes.. the way it works is that when you have multiple APs with the same name it will take the strongest. Within a certain tolerance. However, the ones at the stations seem to over power the ones on the train so you basically always get bumped. If the ones on the train were a little stronger you shouldn't be getting bumped.
